The southern and southwestern sectors show the greatest bathymetric variation in the area, with emergent small islands (such as Dos Amigos, Rafael and Juan Bautista), and a great number of submerged rocks.

This data is then integrated with 3D GIS (A 3D image-analysis zooarchaeological recording system pioneered by Yoshiko Abe and Curtis Marean) based model of the paleolandscape enriched with an integration of bathymetric (study of underwater depth) data and sea level curve allows a multi-faceted reconstruction of this life history-CWM
